Ideal O.E. replacement Q4 Sealed Chain (Q4 seal-ring chain) offers 1.5 to 2 times longer wear resistance than regular O-ring chainsEach refined component designed with computer analysis provides higher tensile strengthSpecially controlled heat treatment means tougher material, more durabilityQ4 seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and fatigue strengthQ4 seal ring offers less friction which leads to less power loss, almost half that of standard O-ring chainRound rivet head offers superior rigidity over 2- or 4-point (quad-staked) rivetingThis new premium chain fits a wider range of machine applications

WARNING: It is vitally important that the chain be correctly matched to the machine size and power output. Failure to do so could result in failure of the chain, resulting in damage to the machine, serious injury to the rider, or even death. You MUST make sure you know which machine you are buying the chain for.
